問題 #21
A data center administrator for a medium-sized manufacturing facility uses Intersight to perform unattended operating system installation on already discovered X-Series servers with server profiles assigned. Which set of prerequisites must be met for installing an operating system on a server in Cisco Mode?

A. configuring a virtual KVM policy
adding a server configuration utility to the software repository
B. adding an OS image to the software repository
adding an operating system configuration file to the software repository
C. configuring a firmware policy
adding an operating system configuration file to the software repository
D. adding an OS image to the software repository
adding a server configuration utility to the software repository

答案：B

解題說明：
In Cisco Intersight, unattended operating system installation requires the OS installation image and the operating system configuration file to be available in the software repository. These files allow Intersight to boot the installer and apply the required unattended installation parameters to the assigned server profile.

問題 #22
An engineer notices excessive broadcast traffic inside a legacy AI server VLAN. Which technology should be implemented to reduce flooding and improve scalability?

A. RIP
B. VXLAN EVPN
C. PAT
D. GRE tunneling

答案：B

解題說明：
VXLAN EVPN reduces unknown unicast and broadcast flooding by using control-plane learning with BGP EVPN. This improves scalability in modern AI data centers. RIP is outdated for large- scale fabrics, while PAT and GRE tunneling do not address broadcast domain limitations.

問題 #23
A network team is configuring quality of service (QoS) for RoCEv2 traffic on a VXLAN fabric. The team must ensure that congestion notification packets (CNP) generated by storage targets are never dropped in the network, as these packets are critical for congestion control feedback. How must CNP packets be handled in the QoS configuration to ensure reliable delivery?

A. Apply traffic shaping to CNP packets to prevent them from causing additional congestion.
B. Configure CNP packets to use the same queue as regular RoCEv2 data traffic.
C. Enable Priority Flow Control specifically for CNP packets on a dedicated CoS value.
D. Classify CNP packets to a high-priority queue using their DSCP marking.

答案：D

解題說明：
CNP packets provide congestion feedback for RoCEv2 traffic and must be delivered reliably so senders can reduce their transmission rate when congestion is detected. Classifying CNP packets into a high-priority queue based on their DSCP marking ensures that these control packets receive preferential treatment and are not dropped during congestion.

問題 #24
A large-scale retail store manages many compute resources spread across branch offices, which enables AI workloads to be processed on-premises. Each workload and site location requires specific OS installation and configuration. To simplify management, configuration, and deployment of the workloads, a Cisco Intersight feature must be used that enables workload deployment at scale. Which feature must be used to accomplish this functionality?

A. chassis management
B. domain management
C. server management
D. fleet management

答案：D

解題說明：
Fleet management in Cisco Intersight is used to manage and deploy workloads consistently across many distributed compute resources. It supports scalable operations such as OS installation, configuration, and policy-driven deployment across multiple servers and locations, making it the correct feature for large distributed AI workload environments.

問題 #25
A network administrator configures RDMA over Converged Ethernet version 2 (RoCEv2). Which transport protocol does RoCEv2 use at Layer 4?

A. UDP
B. TCP
C. ICMP
D. SCTP

答案：A

解題說明：
RoCEv2 encapsulates RDMA traffic over UDP/IP, enabling routable RDMA communication across Layer 3 networks. TCP introduces retransmission and latency overhead unsuitable for high-performance GPU communication. SCTP and ICMP are not used for RoCEv2 transport.
